(Cl. .Z-69) 8 Claims.

My invention relates to door sealing arrangements and its principal object is to provide metal to metal resistance to extension of re on shipboard, either into or out of separate compartments or structure, by way of doors or hatch covers.

A primary feature of the invention consists in providing metal means adapted to resist the passage of re from one side of a ships door to the other which may 'be easily installed or applied after the door is hung' or placed in position and which may be applied to the doors of most ships now in service and in production without making any modification in the structure of those doors.

Another feature of the invention consists in providing plate-like means` rigidly mounted around a door or hatch for overlapping the outer edges of the door or hatch for resisting the passage of fire from one side of the door to the other.

A further feature of the invention consists in providing plate-like means which is capable of being mounted on the door frame or hatch coaming for cooperatingl with the outer edges of the door or hatch to resist the passage of fire.

Other features of the invention, residing in advantageous forms, combinations and relations of parts, will hereinafter appear and be pointed out in the claims.

In the drawings,

Figure 1 is a front View of a bulkhead door and frame embodying the invention, the lower part of the door being omitted to show more clearly parts on the bulkhead which are cooperable therewith.

Figure 2 is a horizontal sectional view of the door and bulkhead shown in Figure l.

Figure 3 is an enlarged sectional view of one edge of the door and the adjoining portions of the bulkhead.

Figures 4, 5, 6, 7, 8 and 9 and are views similar tofligure` 3 each embodying slightly different forms of the invention.

The invention is' shown in the drawings as applied to bulkheads and their associated doors but it will be apparent to those skilled in the art that the invention is not limited to use with bulkhead doors but can be used with equal effectiveness and facility with closures of any type employed on ships, for example, hatch covers.

Referring more particularly to the drawings and specifically to the embodiment of the invention shown in Figures 1, 2 and 3, l indicates a metal door having inturned marginal flanges 2. The

door islshownjin Figures 1 and 2, pivotally connected by suitable hinge members 3 to a bulkhead 4 and any suitable means, such as the we11 known pivoted dogs 5, shown in dot and clash lines in Figure 1, may be employed for locking or securing the door in closed position.

A strip of relatively flexible sealing material 0 of the desired substance is mounted on the inner face of the door adjacent the marginal flanges thereof and it is adapted to be compressed intermediate its edges by a rigid flange 'l surrounding the door opening. This sealing material can be connected to the door in any of the Well known or suitable manners heretofore employed.

In the form ofthe invention shown inl Figures 1, 2 and 3, the sealing material is connected toA the door by a pair of laterally spaced oppositely arranged angle membersV and 9, respectively.

Angle 8 is spot welded or connected in any other desired manner, to the marginal flange of the door while angle 9 may be similarly connected to a bar or plate-like member I0 which is secured, as 'oy welding for example as indicated at Il, to the door adjacent the inner side edge of the sealing material. For sakeV ofvclarity, angles 8 and 9 have been omitted from Figures 1 and 2.

The rigid flange 1 which surrounds the door opening for cooperating with the sealing material is shown in Figures l, 2 and 3 as being an integral part of the bulkhead. The locking or securing dogs 5 force the door inwardly with respect to the rigid flange a sufcient distance to compress nthe sealing material and thereby render the door satisfactorily water-tight. The extent to which one type of sealing material may be advantageously compressed is indicated in dotted lines in Figure 3.

For resisting the passage of fire from one side of the door to the other, metal means is provided for overlapping the outer faces of the marginal flanges of the door. This means is of such c0nstruction that it can, in effect, telescope with respect to the marginal flanges of the door and thus not interfere with closing of the door and compression of the sealing material. In the form of the invention illustrated in Figures 1, 2 and 3, the means for resisting the passage of fire cornprises a flat structural bar i2 which is spaced from and arranged in parallel relation with the rigid flange of the bulkhead. The'inner edge of this bar may be secured in any suitable fashion, such as by welding as indicated at I3, and its outer" end portion is adapted to be in overlapping relation with the outer face of the marginal flanges of the door when the rigid flange of the bulkhead ini tially engages the sealing material. The degree of overlap between the outer portion of the bar I2 and the marginal flanges of the door will, therefore, be as great as the initial amount of overlap plus the amount the sealing material is compressed. The inner corner of the outer edge of bar I2 may be rounded, if desired.

In Figure 4 a slightly different door structure is illustrated. Here the sealing material is secured to the door at its outer edge'by an integrally offset portion I5 of the marginal flange I6 and at its inner edge by an angle I'I which is connected to one flange of a larger angle I8 which may be secured to the door in any .suitable manner and whose other flange is interposed between the sealing material and the door. Moreover, the rigid flange which surrounds the dooi` opening is welded, as indicated at 2l, to the bulkhead instead of being formed integrally-therewith.

The'structural bar 22 shown in Figure 4 cooperates with `the outer face of the marginal flanges I6 of the door in the same manner and Ior'thesame purpose as bar I2, inthe previously described form of the invention, cooperates with 'themarginal flanges of the door I thereof.

` 24 which'is thinnerthan lthe bars I2 and 22 of Figures 3 and 4 but to give it substantially the same rigidity as those 'bars against lateral deflection or bending-its outer end portion is curved as indicated at 25. Itis arranged tocooperate with the marginal anges of the door in the same manner and for the same purpose as the correspondingbarslZ and 22.

In Figure 6, the invention is shown as embodied in'a door construction wherein the bounding or marginal flanges of the door are not disposed at right angles to the'main body of the door. an integral channel-like member 26 is secured 'in any advantageous manner to the edge portions Here of the door and in order that the sealing material l2l may be retained therein without any extraneous means, either or both of the legs or flanges Means 29, l

28 may converge toward each other. like the bars I2 and 22 of Figures 3 and 4, respectively, may be employed to cooperate with the outer leg of the channel in much the same fashion and for the same purpose as the bars I2 and" 22 cooperate with their respective doors. However, when the outer leg of -the channel is oblique with respect to the body of the door as shown, it is not possible to obtain the same degree of telescoping action as where the marginal anges are normal to the door but all telescoping movement ordinarily required between the re resisting member and the door can be obtained by bevelling or inclining the innerface of the outer portion of the bar, as indicated at 30, to the same angle as the outerface of the inclined ilange.

In the forms of the invention illustrated in Figures 7, 8 and 9, the means which overlaps the outer face of the marginal flanges of the door to resist the passage oi ilre is secured to the rigid flange surrounding the door opening for compressing the sealing material, instead ovto the wall of the bulkhead or to the 'deck adjoining the hatch, as shown in the other embodiments of the invention. Mounting the -flre resisting means in this manner is particularly desirable in those cases when the closed door or hatch. is disposed at, such a great distance from adjoining ship structure that the use of a bar or plate, such as I2, 22, 24 and 29 in Figsl 3, 4, 5 and 6, respectively, might not seem suitable.

In the form of the invention illustrated in Figure 7, the door construction is the same as that illustrated in Figure 4 and the member 3l for resisting the passage of iire is a structural Z bar. The Z member is connected to the rigid flange 32 surrounding the opening by spot welding or otherwise securing its inner leg 33 to said flange in such position that the outer leg 34 of the Z will project outwardly into overlapping relation with the outer face of the marginal iianges 35 of the door. The outer ange is of such depth that it may telescope with the door such distance as is necessary to enable the flange to cooperate with the marginal flanges of the door in the same manner and for the same purpose as bar I2 of the embodiment of the invention shown in Figure 3.

It will, of course, be recognized that by using a member of this character the flange which coacts with the outer face of the marginal flanges of the door may be easily bent from its normal position, as indicated in Figure 7, to provide the exact clearance which will permitoperation of the door and yet which will resist passage of re from one side of the door to the other.

In Figure 8, the eiect of a Z member is obtained by welding or otherwise suitably securing two angie bars back to back. In such construction, the leg 36 of one of the angles is secured to the rigid flange 31 surrounding the door opening in such manner that the outer leg 38 of the other angle may overlap the outer face of the marginal anges of the door and cooperate therewith in the same manner as the outer flange 34 of the Z member in Figure '7. The advantage of employing a built up Z member as in Figure 8, instead of the integral one as in Figure 7, is that the two parts of the built up Z can be so connected that the inner and outer legs thereof may be disposed in any desired spaced relationship.

In the form of the invention illustrated in Figure 9, the member for resisting the passage of flre is a reversely bent plate 40. This plate is connected directly to the rigid flange 4I surrounding the door opening so that the outer one of the two reversely bent portions 42 opens outwardly away from the bulkhead or hatch. 'I'he outer leg 43 of this portion is adapted to overlap the outer face of the marginal flanges 44 of the door in the same manner and for the same purpose as the outer leg 34 of the Z member in Figure 7. The distance between the two free legs of a reversely bent member of this character may be easily varied, if necessary, to meet different conditions.

With a bar or other means here described for resisting the passage of fire from one side of the door to the other by coacting with the outside edges or bounding flangesv of the door or other closure, the amount of clearance between the fire resisting means and the door for best meeting operating requirements can be definitely and easily determined. Moreover after being once experimentally determined for a particular type of door, the necessary amount of clearance can be easily reproduced when the fire resisting means is subsequently applied to doors of the same type by merely employing a suitable temporary means of thel required thickness which will afford an actual bearing for fitting purposes against the coacting edge of the door or hatch, Upon removal of the temporary means, such for example as shlms or even palper, the desired condition of operating clearance will Athen exist. It is thus seen that normal operation of the door and effective functioning of the fire resisting arrangement can be readily assured, i

Furthermore, by providing a fire resisting means which overlaps the outer surface of the bounding edge or flange of the door, it will be apparent that its use will require no change or alteration in any part of the door structure. In fitting the fire resisting means to the door, this can be done when the door is in the position of closure it assumes when the sealing material thereof first engages the flange surrounding the door opening or in\ any other further position of closure wherever the bounding flanges are normal to the body portion of the door but when the marginal flanges are oblique to the body portion, as in Figure 6, the fitting can be properly accomplished only whenthe door is in tightly locked position.

Various changes in the details of door construction described and of the particular means described for connecting the various parts thereof may, of course, be made without departing from the spirit and scope of the invention defined in the appended claims.
